Towards 64-bit pageids. bufferManager can handle 64-bit offsets, but recordid.page is still 32 bit...

Added function to handle code that allocates data without first consulting the allocationPolicy
2006-08-11 03:01:16 +00:00
Sears Russell
8faf045e7d
Fixed numerous bugs in allocationPolicy.c and alloc.c
...
allocationPolicy.c was not handling deallocations correctly
Tdealloc() was not calling interpretRid() on its input before passing it into the allocationPolicy
Added locking support for TallocFromPage()

Addded "interpretRid" which knows how to call the "dereference*" functions.

Added assertions to make sure that the region mutex is held when
...
appropriate.

Added logWriter_isDurable. If = 0, then the log will never be forced.
2006-08-10 23:54:46 +00:00

Added logWriter_isDurable. If set to zero, the log will never be forced

to disk.
2006-08-10 23:53:51 +00:00

Force in-flight page file writes to disk before truncating. (Needed if
...
O_DIRECT isn't in use.)
Changed diagnostic messages to go to stderr.

Now, you can set pageFile_isDurable=0 to disable forcing data to the
...
page file.
Also, -DPAGE_FILE_O_DIRECT switches the page file from using a normal
file handle and fdatasync to use O_DIRECT with no fdatasync.

memoized loadPage() (per thread)
...
no longer requires pbl compatibility wrappers
2006-08-10 23:45:25 +00:00
Sears Russell
7847331771
Minor cleanup, added ability to calculate the global average number of
...
buckets traversed per find(). Added a warning for code that actually
relies upon PBL's way of interpreting insert.

Updated X-axis range to better reflect paper.

Test is more stringent now; it runs in roughly the same amount of time
...
becase pageFile.c is no longer using O_DIRECT.

Made a pass on the paper

Needed to protect a linked list with a mutex. It's suprising that this hasn't come up before.
2006-08-08 01:41:45 +00:00

Improved latch profiling, especially for loadPage.

Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier
...
of pages, so it doesn't suggest ones that aren't already in the buffer pool unless it has to.
2006-07-29 00:56:54 +00:00
Sears Russell
783d1d6ffd
Removed the fixed page initialization operations, which weren't being used, and were a slow hack anyway. There is now a more-general (and efficient)
...
implementation in alloc.c
2006-07-29 00:54:01 +00:00

compensations_init() was being called too late.

added colleen, and credits for the libraries that LLADD uses.

78f7b5a12e
Added tests for concurrent transactions + aborts(). Still doesn't test
...
latching, as it is single threaded.
2006-07-27 00:16:24 +00:00

a3d0f6f6f5
Added support for concurrent transactions (by using nested top actions).
2006-07-27 00:15:29 +00:00
Sears Russell
1988cf297d
The "WARNING: Tdeinit() is aborting transaction %d" runtime message now
...
lists the xid of the transaction it's aborting instead of "-1".
TisActiveTransaction(xid) now returns 0 for INVALID_XID. Before the
output was undefined.

Fixed segmentation fault when a CLR with a NULLRID is encountered. I
...
don't understand why this bug wasn't triggered by linearHashNTA or
linkedListNTA, but is triggered by the new region implementation.
2006-07-27 00:10:21 +00:00
Sears Russell
e9880654e4
Added the INVALID_XID constant.

added call to get the page type.

MAX_BUFFER_SIZE can now be specified in CFLAGS.

removed assert() that checks to make sure that Tupdate() didn't pass a page pointer in.
